Can you stack Mazdutide (IBI362) and Tirzepatide?
People sometimes combine peptides that target different pathways, but there is little controlled research on this specific pairing and the interactions aren't well characterized. Because at least one is a research-use compound, we don't publish stacking or dosing protocols here. Any combination should be discussed with a qualified clinician.

Regulatory & legal status
Approval status varies (see the chips at the top). FDA approval and compounding rules for peptides change frequently, and research-use status is not a legal clearance for human use. The FDA does not review compounded drugs for safety, effectiveness, or quality. Verify current status with primary sources before acting. Last reviewed September 21, 2026.
